The pump draws air into the instrument for measurement, and its suction has ten adjustable levels. This configuration provides all four gas channels in one handheld unit, with concentration readings on a dot-matrix LCD and two-stage sound and light alarms.\u003c\/p\u003e\u003ch3\u003ePumped Sampling and Daily Controls\u003c\/h3\u003e\u003cp\u003eThe sampling pump has a maximum flow of 1 L\/min. The LCD shows the gas type, concentration, measurement unit, time and battery status; English and Chinese interfaces are available. Temperature and pressure compensation are built into the measurement functions.\u003c\/p\u003e\u003cp\u003eSelf-calibration, zero calibration and a factory reset are available through the instrument controls. Alarm set points can be adjusted for the monitoring procedure.
